[Serious] Why don’t our parents respect our choices

Every trip I take with my mom it inevitably comes up how it’s possible to travel and have a good life with kids. I firmly tell her I know that’s true, but that’s not the life my husband and I have chosen. We are set in our decision to be child free. She ends up in tears then I feel sad/mad that she doesn’t respect my decision as a full blown adult. I loved growing up with a family of 6 and my siblings have 12 kids (a few step kids mixed in) so she already has grandkids to dote on.
